The integrated instrument testing device integrates instrument calibrator, instrument testing platform, current voltage load box, and instrument error management system (software) into one. All operations are controlled by computer, with fully automatic measurement (including error data under light load), simple, convenient, and reliable.
◆ The device uses programmable source technology for fine adjustment, making the positioning of the test points faster and more accurate;
◆ The device has significantly improved the measurement speed of multiple current transformers. It can measure twelve current transformers of any ratio within 3-5 minutes;
◆ The device is equipped with 1A and 5A standard current transformers. The current load box is configured with 1A and 5A load values of 2.5VA-80VA, and the voltage load box is configured with 100V and 100/1.732 load values ranging from 1.25VA-158.75VA, which basically meets user requirements. The load box can be automatically switched during measurement;
◆ The device can perform both standard and non-standard measurements of mutual inductors, and users can specify measurements at any percentage point during measurement.
◆ Environmental conditions for device use:
Temperature: 5℃~40℃
Supply voltage: 220V±5V
◆ Parameters of high-speed instrument calibrator
